>>1232951>Pic related It may be a bit off topic as a whole, but there is one chapter where Bernd Heinrich gets pretty philosophical and makes some very compelling theories about why we enjoy being in nature.
His reasoning would be scientifically hard to prove, but so is any theory posted about the evolution of the mind. It's a great read nonetheless and I recommend it if you have any interest in cognitive psychology of other creatures and of ours as well.
